antitsüklonid

Antitsüklonid, also known as high-pressure systems, are large-scale weather phenomena characterized by high atmospheric pressure at their center. These systems typically form when descending air in the upper atmosphere cools and spreads outwards at the surface. In the Northern Hemisphere, anticyclones are associated with clockwise wind patterns, while in the Southern Hemisphere, the winds rotate counter-clockwise. The air within an anticyclone generally sinks, which suppresses cloud formation and leads to clear skies and calm weather. This sinking air also causes any moisture present to dissipate, further contributing to dry conditions. As a result, anticyclones are often linked to periods of stable weather, including sunshine and warmth in summer, and cold, clear conditions in winter. They can persist for several days or even weeks, influencing weather patterns over large regions. The presence of an anticyclone typically means fair weather, with a lack of precipitation and often reduced wind speeds near the center. They are a fundamental component of atmospheric circulation and play a significant role in determining daily weather.
